Item
is
used
and in good condition. Rack ears are included as shown. This
is the NENA version of the
9483 - the firmware is the same as the regular units so the
NENA option
card can just be ignored if you don't plan on using those
interfaces.
The unit has been tested to confirm that it works as it should
-
screenshots of the actual item under test are shown below.
This model
has a GPS receiver to maintain accurate time with a roof
mounted antenna. This unit also has the upgraded OCXO
oscillator for better free-running stability. It has been
tested to
confirm that it works as it should. The screenshots show the
actual unit
for sale undergoing testing. The firmware is the latest
version
available at the time of listing (v5.9.4). No antenna is
included but
almost any professional 5V conical antenna should work well
provided
that it is located outdoors with a full view of the sky. I can
provide a
recommendation if required. The photos show the actual item
for
sale.
